00:00:02,498 --> 00:00:13,028
0012 became 12. Compare raw strings before deciding how to repair data.

2
00:00:13,028 --> 00:00:24,085
Missing is not empty. The report keeps the distinction visible.

3
00:00:24,085 --> 00:00:35,110
Duplicate keys are unresolved. Do not pretend to know which rows match.

4
00:00:35,110 --> 00:00:44,200
An unchanged control completes the check. Destination behavior still needs testing.
